Ronald McDonald has replaced his passé overalls with a chic vest and pants combo, showing that just because you're a clown, you don't have to look like one.The Associated Press reports it is all part of a new campaign by McDonald's to boost weak sales. Ronald left the spotlight a few years ago, keeping a low profile due to criticism from activists who thought he was peddling unhealthy food to children. Now he's back with a new look and an appreciation of social media: Ronald is going to become active on Twitter, using the hashtag #ronaldmcdonald to share photos and videos (according to the AP, Ronald will not have his own handle, at least not yet)."Selfies…here I come! It's a big world and now, wherever I go and whatever I do…I'm ready to show how fun can make great things happen," the character said in a statement.The world's most famous clown may be wearing new digs, but one thing that hasn't changed is his taste in footwear. "His iconic big red shoes will remain the same," McDonald’s said in a statement. Watch a video of Ronald's transformation below. --Catherine Garcia
